Newly designed Hagglunds hydraulic motors from Bosch RexrothBosch Rexroth has improved the design of its compact series of Hagglunds hydraulic motors, giving the range unmatched power density and the ability to deliver full torque and full speed simultaneously.

The new Hagglunds CA 10 to 40 motors are far smaller and lighter in design, but still maintain the same operational levels of the previous version. The improvements see the hydraulic motor extend down to 10Nm/bar.

With extreme power density and high flexibility, the new motors are well suited for use in lighter applications, such as injection moulding machines in the plastics industry. The new design has seen Rexroth reduce the motor diameter whilst refining the internal construction. The improved motors deliver more kilowatts of power per kilo than any other. Full speed and full torque are available simultaneously, and both can be sustained for an indefinite period of time.

The new series is available in four basic models, as well as a wide variety of displacement versions. The torque can be configured via two mechanical interfaces to meet bespoke needs, keeping tight dimensioning and optimisation with hydraulic pumping systems simple.

In addition, the new Hagglunds motor utilises hydraulic radial piston motors with a built-in ability to withstand shock loads. It also features perfect internal symmetry, enabling not only consistent torque throughout the revolution, but a balance of forces, minimising noise and vibration.

David Waldron, Business & Divisional Manager at Bosch Rexroth, says: “The streamlined design of the new Hagglunds hydraulic motor allows engineers to utilise the operational capabilities the market place has come to expect from the Hägglunds series in smaller applications. The new Hagglunds CA 10 to 40 motors not only offer unrivalled power density, but the design improvements have reduced hydro-mechanical losses in the motors, enhancing energy efficiency levels.”
